INVENToRs. John lasenbrock, BYz/oseph K, Cnagan` M ATTORNEY i Patented May 3o, 1933 vas shown as slight one side thereo UNITED STATES PATENT oFFlcE JOHN DASENIBROOK AND JOSEPH A. CRAGAN, 0F POUGHKEEPSIE, NEW' YORK fGUARD ATTACHMENT FOR WBINGERS Application led August 31, 1932. Serial No. 631,144.

This invention relates to an attachment for clothes wringers, and the primary object of the invention is to provide a guard for the power driven clothes wringers o f washing machines, which is s o designed that the easy feeding of the clothesv in between the wringer rolls is permitted but the possibility of the operators fingers being caught in the rolls is prevented.

Another object of the invention is to provide a guard in the form of a simple; durable and cheap attachment that can be mounted upon .any of the well known power wringers.

A further object is to provide means in a guard of this kind, whereby the clothes may be readily fed to the rollers in such a manner that it will be impossible for the lingers of the operator or caught by the rollers, and also to provide means whereby-the sides of the device are also protected in such a manner that a child can not reach the rollers through the sides of the guard, as is now the case with other devices intended for this purpose.

Another object of the invention is to provide means whereby the sight feed of the clothes between the wringer rolls is not obstructed in any manner, and yet the rollpass is fully protected and can not be reached by the hands except for cleaning or, clearing the rolls.

With these and other objectsfin view, our invention consists in certain novel construction and combination of parts as will hereinafter be fully described and claimed in the annexed specification, and fully illustrated in the accompanying drawing in which like figures of reference refer to corresponding parts in all of the views, but we do not confine ourselves to the exact design changes may be made without departing from the spirit of the invention. In the drawing Figure 1 is a top wringer, showin the other side showing partly in section. v

Figure 2is a side elevation of the device,

to b ecome engaged plan view of 'la powerv the device attached tol showing the same as attached to wrlnger.

Figure 3 shows an enlarged partial view of a corner of the guard plate, to illustrate the method of locking the same to the frame. Figure 4 shows a partial inside view of one of the side frames, with the wringer rolls in section, and the conveyor belt in place, with a bunch of clothes passing under one of the idler rolls upon the belt to the wringer rolls.

Figure 5 shows an end elevation of the device as applied to a power wringeny Figure 6 shows of, one of the upper corners of the guard plate, illustrating the method of mounting the same to the side frame. Referring to the drawing- We have herewith indicated the usual type of power driven wringer, comprising the roller supporting posts 10, within which are rotatably mounted the wringer rolls 11 which are rotated in opposite directions by the vpower driven gear box 13 which is mounted upon :one of the posts 10.

The wringer'is also provided with the usual roll adjusting means 14 and 15, and suppliedl with the dri pan 16.

Our guard attac ment comprises the two a power side frames 17 which are connected at one fr" end by the channel shaped member 18 which embraces one of the supporting posts 10,. as shown in Figures 2, and 5; the other side frames 19 are also connected together b a channel member 20 which embraces the ot er Y lsupporting post 10; this member 2O bei provided with the ears 21 to which is bol the gear box 13 by the bolts 22, thus attaching the guard `frames to the wringer in a detachable manner. g

The guard side frames 17 and 19., are formed with a wing or closed portion 23 to prevent access to the wringer rollers 11 from the side and any danger of the operators fingers coming into contact with the rollers from the side. a

The guard sides 17 and 19 are also formed with an arm integral therewith and projecting therefrom at an angle thereto, and in the outer ends of these arms 24 are formed a partial enlarged view,

slotted bearings within which are adjustably secured by the nuts 26 the ends of a threaded shaft 27 upon which is mounted in a freely rotatable manner a roller 28 of some suitable material such as rubber'and which is slightly crowned in the center.

Adjacent the junction of the arm 24 and the wing 23 is formed alined bearings 29 within which are freely mounted the ends ofthe shafts 30 which carry the idler rolls 31, which may also be of rubber or other suitable material; while adjacent the upper part of the wings 23 are the bearings 32 within which are mounted the trunnions 33 which carry the hinged guard late 34.

Around the rollers 28 and tween the power wringer rollers 10 is passed an endless belt or conveyor 35 which is made of rubber or other suitalle resilient material that has a considerable amount of stretch;

' this belt 35 passing under and normally in contact with the idler rollers 31, but due to its elongating qualities allowing the clothes 36 to pass between the belt 35 and the roller 31.

The idler roller 31 being mounted on the same plane as the center of the power wringer roller 10, and thus below the roll.- pass, the lingers of the operator while in the act of feeding the clothes upon the belt 35 and under the roller 31 can not in any manner reach the roll-pass; and the clothes passing upon the conveyor belt 35 and in contact with the idler roller 31 are partly pressed before reaching the wringer rollers 10.

For effecting a guard for the roll-pass and at the same time not affecting' the sight feed of the clothes tothe roll-pass, and also for preventing any clothes from passing around the roller 31 and not entering the roll-pass,

we have 'provided a guard plate 34 comprising a frame within which is mounted a yglass 37 said frame 34 being provided with a pair of trunnions 33 by which it is hin ed at the top to the side frames 17 and 19, w ile at its lower ed e it is 38 by which it is ocked in place to the side frames in such a manner that it may be raised for cleaning the wringer rollers 10 and removing any clothes that may become clogged between the rollers 10; and at the same time it will prevent any clothes from passing around the roller 31 and act as a guide to the roll-pass.

Having thus described our invention, whatwe claim as new rand desire to secure by Letters Patent, is-

, A guard attachment for ower clothes wringers, comprising in com inationv with wringer supporting posts and rollers, of

side frames formed witha channel portion lto embrace lsaid supporting posts and def tachabl secured thereto, armsformedl on said si e frames and projecting below the' rovided with two latches lower wringer roll, rollers mounted in said arms, idler rollers mounted in said frames above said rollers and below the roll-pass of the wrin er rollers, an endless resilient com veyor be tmounted on said rollers and passing between said roll-pass and in contact with the idler rollers, and a guard late mounted in said side frames above the idler rollers and adjacent the roll-pass.

In testimony whereof, we aix our signatures.
